Full Duplex mode

553-3001-368 Standard 26.00
The IP Phone 2001 registers with the TPS and, if needed, begins the
firmware download. This takes several minutes. When the download is
complete, the IP Phone 2001 resets.
Note: The Enhanced UNIStim Firmware Download feature for IP Phones
provides an improved method of delivering new firmware to IP Phones.
For further information on Enhanced UNIStim Firmware Download, see
IP Line: Description, Installation, and Operation (553-3001-365).
The current system date and time appear on the top line of the display
when the configuration is complete. Self-labeling keys also appear.
9 Check for dial tone and the correct DN above the display.
10 (Optional) Customize the feature keys as required. For more information,
see IP Phone 2001 User Guide.
In the Configuration menu, Auto Negotiate mode is the default setting for
initial startup. Typically, the IP Phone is connected to a network that supports
Auto Negotiate, and it selects the best speed and duplex mode available.
There is no intervention required under normal operation.
Note: Changing the speed and/or duplex mode on the phone changes
both the LAN Ethernet port and PC Ethernet Port interfaces.
It is recommended that Auto Negotiate mode is used on the network
and the IP Phone. Use Full Duplex mode only when the network is
forced Full Duplex for 100BT Full Duplex mode, otherwise a duplex
mismatch will result.
If the IP Phone is connected to a network configured for Full Duplex mode
only, the IP Phone cannot automatically negotiate the proper configuration.
Therefore, in this instance, to allow the IP Phone to work at the optimum
speed and duplex mode, Full Duplex mode must be enabled.
